Question

Hydrogen has been used as rocket fuel .Would you consider it cleaner fuel than CNG ?Why or why not?

Answer 1

Heya!

Here is ur Answer :-P

=>Hydrogen is a cleaner fuel than CNG. This is due to the reason that it produces water on burning whereas CNG on burning produces CO2, though much less than that produced when coal or oil is burnt. The increase in concentration of CO2 in the atmosphere increases the temperature of atmosphere.

Answer 2

$\huge\mathbb{\underline{Answer:-}}$

Hydrogen is a cleaner fuel than CNG because when hydrogen is burnt only water vapour is produced which is not harmful to environment.

However, CNG on being burnt produces carbon dioxide along with water vapour.

Additionally if CNG undergoes incomplete combustion, carbon monoxide is produced instead of carbon dioxide which is much more dangerous and harmful for us.

Besides this certain additives and impurities are also present in CNG which when burnt produce dangerous oxides of elements like sulphur, nitrogen etc.
